To all whom it may comm m:

Be itv known that I, ANTONIO G. B'AVA, a subject of the King of Italy,residin at city and county of San Francisco and tate of California, haveinvented a.- new and useful Improvement in Belting Tools, of which thefollowing is a. specification.

This invention relates to a belting tool.

It is the principal object of the present invention to provide as toolwhich may be used tosecure the ends of belting together wnd mrticularlyadapted for cutting and stapling the ends of round belt cords inposition relative to each other so that a continuous belt will beprovided.

The present invention contemplates the use of a device having three 'ewshinged together at one end and adapts to be separately moved to cutbelting, thereafter grip the ends of e belt in abutting relation to eachother, then force a staple through the belt and crimp the same inposition.

The invention is illustrated by way of example in the accompanyingdrawings, in which:

Figure 1 is aview of the belting tool in elevation. with the pressurejaw turned back and with parts of the clamping jaw broken away to moreclearly show the position of belting secured thereby.

Fig. 2 's a view in side elevation showing the parts disclosed in Fig. 1and further indicating the stapling operation.

Fig. 3 is a view in section through the device as seen on the lines 3-3of Fig. 2 showing the manner in which the staple is forced through thebelt.

Fig. 4 is another view showing the staple as it has been completelyforced through the belt and particularly bent over.

Fig. 5 is a view in section through the tool as seen on the line 5--5 ofFig. 2, showing the manner in which the staple is set in position.

Fig. 6 is a view showing parts as illustrated. in Fig. 5 disclosing thecompletion of the setting operation.

Referring more particularly to the drawings, 10 indicates a. clampingjaw which is formed with a handle 11. This jaw is pro vided with a hingebar 12 at its end which clamping action of the two jaws l0 and 14.

The second or intermediate clamping jaw 14 is formed with centrallongitudinal openings 17 which as shown in Fig. 1 gradually enlargestoward the handle of the jaw. thus accommodating larger staples 18 forthe larger sizes of belting. Grooves 19 extend along the opposite sidewalls of the opening 18 and: act as guides for the staples. Thesegroovesare so disposed as to direct the points of the staples throughthe center of the belting held within the recesses of the clamping jaws,thus insuring that the staples will be oent'ral'l driven through thebelting. Directly he ow the guide slots 1'9 and formed within the lowerjaw 10 is a series of recesses 20 into which the points of the staplessire forced, after having passed through the belting and by which theends of the staples are bent so as to prevent their removal from thebetting. It is to be understood that these staples are of special shapeas shown in Fig. 3 amd that by reason of their straight sides andtapered points it is possible to easily inturn them as they are forceddown along the inclined faces of the recesses 20.

The staples are forced through the belting by means of a pressure lever22. This lever is pivoted upon a pin 23 to the upper end of the hingemember 12 and may be swung toward and away from the clamping jaws and inthe same plane of swinging movement as they pursue; The )ressure jaw 21is secured to the face of the ever 22 and is adapted to be passed intothe open- 18 in the secondary clamping jaw 14. The shape of the block issubstantially the same as that of the opening 18. thus providing apressure surface agreeing with the flat up per face of the staple to beset. At the end of the clamping jaws near the handles recesses 24. areprovided. These recesses are adapted to accommodate the belting afterthe staple has been passed therethrough and from gripping means so thatan extension 25 may be brought down against inturning ends of the stapleto cause them to be satisfactorily set as more clearly shown in Fig. 6.

For convenience a cutting blade 26 is secured to the pressure lever 22and is adapted to move down alongside of the member 14 so that thebelting may be easily cut. A centering blade 27 is also provided and isadapted to extend across the grooves a, b, c, and d of the lowerclamping jaw. This makes it possible to center the joint of the beltdirectly in the center of the staple.

In operation of the present invention the belting is cut to a suitablelength by means of the cutting blade 26, after which the ends of thebelt are placed in one of the recesses in the lower clamping jaw 10 withtheir end faces abutting against the opposite sides of the centeringblade 27. The secondary clamping jaw 14 is then brought down over thebelt and the two jaws locked in relation to each other by a ring member28. The staple ,18 is then placed in the slots 19 of the secondaryclamping jaw and its points directed downwardly against the belting. Thepressure jaw is then forced down and will drive the staple through thebelting and force its points into the narrow recess 20 where the pointswill be inturned as more clearly shown in Fig. 4. After this has beenaccomplished the jaws 10 and 14 are opened and the belt turned over andlaced with the flat portion of the staple within recess 24 of theclamped jaw 10. The belt is again clamped in position and pressureexerted upon the inturned points of the staple by the projection 25 ofthe pressure block 21.

It will thus be seen that the present invention provides a very compacttool by which belting may be cut and securely stapled at its ends, saidtool operating in a manner to insure that the staple will pass directlythrough the transverse center of the belting and will thereafter beclinched in a secure manner.

While I have shown the preferred form of my invention as now known tome, it will be understood that various changes in the construction,combination and arrangement of parts may be made by those skilled in theart without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1. A belt stapling device comprising a fixed jaw with transverse beltreceiving grooves. a clamping jaw pivotally connected to the fixed jawand having portions engageable with the belt ends disposed within thegrooves, and a pressure lever fulcrumed near the first named pivot andmovable to force a staple through the ends of a belt placed in one ofsaid grooves.

2. The combination in a belt stapling apparatus, of a fixed and amovable jaw, transversely grooved to receive the contiguous belt ends,said movable jaw having a longitudinal vertical opening, and a pressurelever having an element extending into the opening and acting to drivethe staples through the abutting belt ends.

3. The combination in a belt stapling device, of a fixed and a movabletransversely grooved jaw to receive and clamp contiguous belt ends, saidmovable jaw having an outwardl divergent recess with vertical grooves toreceive the staples, a movable lever having a portion insertable withinthe divergent recess in the movable jaw to engage the staples and forcethe same through the contiguous ends of the belt.
